I am puzzled as to why you would even want to compare CGIDEV2 with a javascript library like ExtJs. CGIDEV2 is just a shorthand term for a service program that simplifies (for RPG developers) the way you can retrieve data an HTTP request and return HTML/CSS/Javascript etc back to the browser. You don't code a UI with CGIDEV2, you just use to deliver content. Our UI is virtually all jQuery based now, but it is delivered to the browser by CGIDEV2 procedure calls (mostly). I expect powerExt delivers ExtJs based content using CGIDEV2 also.
I guess what I mean to say is that using CGIDEV2 does not preclude you from using ExtJs or jQuery or Glow or any other rich UI you care to use. I can't remember when I last bothered to fiddle with some HTML template to create a UI - which I guess is the way one is taught to use CGIDEV2 when you first play with it. Is it the latter technique to which you allude?

Hi Nathan,
I fully agree that JSON and ExtJS syntax is messy. The JSON
messy-ness is resolve by having JSON composer/parser on both ends (in
ExtJS and RPG), and the Firebug plugin for Firefox has a nice JSON
renderer that I use for debugging.
The ExtJS syntax I am still working on. I hope to eventually store
the properties of a screen/panel in a DB2 table and have "render kits"
that take the DB2 data and render it to a particular UI framework
(i.e. ExtJS, SenchaTouch, jQTouch, Android, iPad, etc).
In the end though, I would still argue that even with the messy ExtJS
syntax it is much easier/quicker for me to code an application than
CGIDEV2. After awhile you get good at the syntax - it's just
Javascript arrays.

I am also liking how these latest js frameworks are allowing and
focusing on configuring "screens" and all we need to do is show/hide
them and occupy them with information. Soooo much easier than the
traditional CGIDEV2 I grew up on - at least in my opinion.
Now I'm curious what you like about "configuring screens"? Looking at an HTML
page source where ExtJS code was for "configuring screens" makes me wonder what
you like about it? I find that long streams of JSON formating are hard to read
and hard to maintain, particularly with all the delimiters. One of the guys in
our user's group is learning Valence, and commented that the RPG code is fine,
but the JavaScript is hard. I assumed he meant that coding in JSON is hard.
